Clang!
Software While I am a Mac guy, this is one of the reasons I love free/open source software ^_^.
clang: noun 1. A loud, resonant, metallic sound. 2. The strident call of a crane or goose. 3. C-language family front-end toolkit. The goal of the Clang project is to create a new C, C++, Objective C and Objective C++ front-end for the LLVM compiler. Its tools are built as libraries and designed to be loosely-coupled and extensible.
